Braking in Emergencies
ABS allows the driver to steer and brake at the same
time. In many emergencies, steering can help more
than even the very best braking.
Brake Assist
This vehicle has a brake assist feature that responds to
emergency braking by generating additional pressure
and engaging the ABS. When this happens, the brake
pedal will feel easier to push. Just hold the brake pedal
down firmly and let the system work for you. You might
feel the brakes vibrate or notice some noise, but this is
normal. The brakes will return to normal operation after
the brake pedal is released.
Brake assist cannot compensate for unsafe driving
practices and braking effectiveness, itself, depends on
the condition of the road, tires, and brakes and
vehicle mass.
Traction Control System (TCS)
The vehicle has a Traction Control System (TCS) that
limits wheel spin. This is especially useful in slippery
road conditions. The system operates only if it senses
that the rear wheels are spinning too much or are
beginning to lose traction. When this happens, the
system works the rear brakes and reduces engine
power (by closing the throttle and managing engine
spark) to limit wheel spin.
The TRACTION SYSTEM ACTIVE message displays
on the Driver Information Center (DIC) when TCS is
limiting wheel spin. See DIC Warnings and Messages
on page 4‑52. The system may be heard or felt while it
is working, but this is normal.
If cruise control is being used when TCS begins to limit
wheel spin, the cruise control will automatically
disengage. Cruise control may be reengaged when
road conditions allow. See Cruise Control on page 4‑7.

Street High Performance Brake Burnishing
Procedure
Run this procedure in a safe manner and in compliance
with all local and state ordinances/laws regarding motor
vehicle operation. Run this procedure only on dry
pavement. 1. From a stop, accelerate as rapidly as possible without activating traction control to a speed
of 97 kph (60 mph).
2. Use enough pedal force to completely stop the vehicle in 4 to 5 seconds. If ABS activates, braking
is too hard.
3. Repeat steps 1 and 2, 50 times. This should take about 10 minutes.
4. After completing the 50 stops, cool the brakes by driving for 8 km (5 miles) at 97 kph (60 mph).
As with all high performance brake systems, some
amount of brake squeal is normal.
Racing/Track Brake Burnish Procedure
To prepare the ZR1 brake system for track events and
racing, the Street High Performance Brake Burnish as
described previously should be completed.
In addition to completing the Street High Performance
Brake Burnishing Procedure, the following additional
procedure needs to be completed to make the
ZR1 brake system ready for track events and racing.
This procedure should only be run on a track and only
on dry pavement.
Notice: Brake pedal fade will occur during this track
burnish procedure and can cause brake pedal travel
and force to increase. This could extend stopping
distance until the brakes are fully burnished.
1. Drive a normal first lap and not too aggressive.
2. Laps 2 and 3 should be gradually driven faster and more aggressive, while allowing for reduced brake
output and increased stopping distance due to
brake fade.
3. Lap 4 as near to full speed, while allowing for reduced brake output and increased stopping
distance due to brake fade.
4. Laps 5 and 6 should be cool down laps
5. Lap 7 should be normal driving or an easy out lap.

TheAntilock Brake System (ABS)on page 5‑5improves vehicle stability during hard stops on a
slippery roads, but apply the brakes sooner than when
on dry pavement.
Allow greater following distance on any slippery road
and watch for slippery spots. Icy patches can occur on
otherwise clear roads in shaded areas. The surface
of a curve or an overpass can remain icy when the
surrounding roads are clear. Avoid sudden steering
maneuvers and braking while on ice.
Turn off cruise control, if equipped, on slippery surfaces.
Blizzard Conditions
Being stuck in snow can be in a serious situation.
Stay with the vehicle unless there is help nearby.
If possible, use the Roadside Assistance Program
on
page 8‑7. To get help and keep everyone in the
vehicle safe:
.Turn on the Hazard Warning Flasherson
page 4‑3.
.Tie a red cloth to an outside mirror.
{WARNING:
Snow can trap engine exhaust under the vehicle.
This may cause exhaust gases to get inside.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
If the vehicle is stuck in the snow:
.Clear away snow from around the base of
your vehicle, especially any that is blocking
the exhaust pipe.
.Check again from time to time to be sure
snow does not collect there.
.Open a window about 5 cm (two inches) on
the side of the vehicle that is away from the
wind to bring in fresh air.
.Fully open the air outlets on or under the
instrument panel.
.Adjust the Climate Control system to a setting
that circulates the air inside the vehicle and
set the fan speed to the highest setting.
See Climate Control System in the Index.

Checking Coolant
1. Verify that the engine and intercooler are no longer hot.
2. Place a cloth to absorb possible coolant loss under the driver's side bleeder valve (A). 3. Loosen, but do not completely unscrew the bleeder
valve to check for coolant in the system.
4. Tighten the bleeder valve if there is coolant flowing out of the bleeder valve.
5. If there is no coolant flowing out of the bleeder valve, there could be a leak in the system. Tighten
the bleeder valve and contact your dealer/retailer
for service.
Engine Coolant
The cooling system in the vehicle is filled with
DEX-COOL®engine coolant. This coolant is designed
to remain in the vehicle for five years or 240 000 km
(150,000 miles), whichever occurs first.
The following explains the cooling system and how
to check and add coolant when it is low. If there is
a problem with engine overheating, see Engine
Overheating on page 6‑38.

If the low-beam headlamp needs to be replaced, see
your dealer/retailer. See High Intensity Discharge (HID)
Lighting
on page 6‑56for more information.
To replace a high-beam or front parking/turn signal/
DRL bulb: 1. Turn the wheel to allow access to the wheel well.
2. Remove the three outer fasteners to move the access panel back. 3. Remove the outer cover to expose the high-beam
headlamp bulb socket.
4. Remove the headlamp
bulb by releasing the
outer tabs from the
socket.
5. Remove the front parking/turn signal bulb by turning the bulb socket counterclockwise.
6. Replace the high-beam headlamp bulb with a new bulb and reattach to the bulb socket.
Replace the front parking/turn signal bulb by
turning the bulb socket clockwise.
7. Reverse the Steps 2 through 4 to reinstall.

Taillamps, Turn Signal, and
Stoplamps
To replace a stoplamp, taillamp/turn signal bulb: 1. Remove the screw from the top of the lamp assembly.
2. Tilt the lamp assembly toward you.
3. Turn the bulb socket one-quarter turn counterclockwise and pull it out. 4. Pull the bulb straight out to remove it from the
socket.
5. Push the new bulb in the bulb socket until it snaps into place.
6. Reinstall the lamp assembly by first lining up the tabs on the bottom of the lamp assembly with the
tabs in the vehicle, then slide it in.
7. Replace the screw at the top of the lamp assembly.

Do not clean the vehicle using:
.A knife or any other sharp object to remove a soil
from any interior surface.
.A stiff brush. It can cause damage to the vehicle's
interior surfaces.
.Heavy pressure or aggressive rubbing with a
cleaning cloth. Use of heavy pressure can damage
the interior and does not improve the effectiveness
of soil removal.
.Laundry detergents or dishwashing soaps with
degreasers can leave residue that streaks and
attracts dirt. For liquid cleaners, about 20 drops
per gallon (3.78 L) of water is a good guide.
Use only mild, neutral-pH soaps.
.Too much cleaner that saturates the upholstery.
.Organic solvents such as naptha, alcohol, etc. that
can damage the vehicle's interior.
Fabric/Carpet
Use a vacuum cleaner with a soft brush attachment
frequently to remove dust and loose dirt. A canister
vacuum with a beater bar in the nozzle may only be
used on floor carpet and carpeted floor mats. For any
soil, always try to remove it first with plain water or club
soda. Before cleaning, gently remove as much of the
soil as possible using one of the following techniques:
.For liquids: gently blot the remaining soil with a
paper towel. Allow the soil to absorb into the paper
towel until no more can be removed.
.For solid dry soils: remove as much as possible
and then vacuum.
